Methodology

Methods:

Two rows of cover crops, each spaced 7.5 in. apart, were drilled between 30 in. wide soybean rows during flowering (R1/R2).  A drill interseeder mounted on a 3 point hitch capable of seeding 5 soybean inter-row spacings at a time was used to perform the operation.  Plots were 30-40 ft long and were harvested with a plot combine on Oct. 19.  Biomass sampling was performed in late-Nov.

Results

Results: The results show there was no significant yield differences among landscape positions although cover crop biomass differed significantly by landscape position, cover crop biomass was greatest on the backslope landscape position. In this study it appears cover crops had no significant impact on yield by the 95% confidence interval.
